You didn't mention what type of application this is being run from. I
have two suggestions for error checking, don't know if they will help.
The first is that if you are getting errors, you won't be able to see
them unless you are running from a console application (or unless you
set up a trace appender to grab the errors, I haven't done that so
you'll have to google for it). This will tell you if the problem is
with the error logging itself.
The second is a method which will tell you how your log4net is
configured. It's written in C#, so you may need to translate. This
should tell you if it is your log4net configuration process which is
going astray.
public static string GetHierarchyInformation() {
Hierarchy hier = (Hierarchy)LogManager.GetRepository();
StringBuilder sb = new StringBuilder();
// first, look for it in the root
sb.AppendLine("Root Information:");
sb.Append(" Name: " + hier.Name);
sb.AppendLine(" Threshold: " + hier.Threshold.ToString());
sb.Append(" Root Appenders: ");
foreach (IAppender a in hier.Root.Appenders) {
sb.Append(a.Name + ", ");
}
sb.AppendLine("");
sb.AppendLine("Hierarchy Appenders:");
foreach (IAppender a in hier.GetAppenders()) {
sb.AppendLine(FormatAppenderLine(a));
}
sb.AppendLine("Loggers:");
foreach (ILogger l in hier.GetCurrentLoggers()) {
Logger log = (Logger)l;
sb.Append(" " + log.Name);
sb.Append(" Additivity: " + log.Additivity.ToString());
sb.Append(" Level: ");
if (log.Level == null) {
sb.Append("null");
}
else {
sb.Append(log.Level.ToString());
}
sb.AppendLine("");
foreach (IAppender appender in log.Appenders) {
sb.AppendLine(FormatAppenderLine(appender));
}
}
return sb.ToString();
}
private static string FormatAppenderLine(IAppender appender) {
StringBuilder sb2 = new StringBuilder();
sb2.Append(" Appender: " + appender.Name);
sb2.Append(" Type: " + appender.GetType().ToString());
if (appender is log4net.Appender.FileAppender) {
FileAppender app = (FileAppender)appender;
sb2.Append(" File: " + app.File);
}
else if (appender is log4net.Appender.RollingFileAppender) {
RollingFileAppender app = (RollingFileAppender)appender;
sb2.Append(" File: " + app.File);
}
else if (appender is log4net.Appender.SmtpAppender) {
SmtpAppender app = (SmtpAppender)appender;
sb2.Append(" To: " + app.To);
}
return sb2.ToString();
}

Subject: Trying to set up an EXTREMELY SIMPLE event log feature... and
failing terribly! Please help a newbie
Hi and thanks in advance for the help.
I'm tearing my hair out over here trying to get this to work: a siple
logger
that writes to the application section of the event log.
This is using log4net 1.2.10.0
Here is the app config:
--------------------------------------------------------------
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<log4net>
<appender name="EventLogAppender"
type="log4net.Appender.EventLogAppender" >
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger
[%property{NDC}] - %message%newline" />
</layout>
</appender>
<root>
<level value="ALL" />
<appender-ref ref="EventLogAppender" />
</root>
</log4net>
</configuration>
--------------------------------------------------------------------
here is my code:
log4net.Config.XmlConfigurator.Configure();
logger = LogManager.GetLogger("EventLogAppender");
logger.Error("test");
-------------------------------------------------------------------
No errors, nothing happens! I notice that there are no appenders.
nothing is written to the event log.
I am tearing my hair out trying to figure out what is going on, can
somebody
help?
